I haven't been through all of my games but actualy:
lunar silver star harmony undub
valkyrie profile
crush (eu)
kingdom hearts bbs (eu)
parappa the rapper (eu)
prince of persia rival swords
silent hill origins (eu)
All crash with the same error (blackscreen then error at launch) I'm on ark-4 4.18.7 (yesterday's build) no plugin. Henkaku enso 3.60. That's about 1 on 4 games.
I don't know if they launched on previous build cause I didn't try them then.
Also tony hawk's project 8(eu) gets stuck on memory stick verification at launch (with and without High speed memory stick option).
So, you're also having black screens?
